CVE-2026-74369

A flaw was found in the Linux kernel's liveupdate component. This use-after-free vulnerability occurs due to an incorrect order of operations when managing file handler modules. Specifically, the system attempts to access module operations after the module's reference count has been decremented,...

CVE-2026-58087

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...

EUVD-2026-62338

To retrieve the previous timer value, the kernel calls realtimergettime, which obtains the current time for the timer's clock. For a timer using CLOCKTAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized output buffer was copied to...

CVE-2026-49428

Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...

CVE-2026-49422

The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...

CVE-2026-49428 posixshm: system calls can incorrectly free memory of largepage objects

Certain system calls, such open2 with the OTRUNC flag set, and fspacectl2, could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug to access freed kernel...

CVE-2026-49428

In FreeBSD's posixshm module, open(2) with O_TRUNC and fspacectl(2) failed to verify whether operations are permitted on largepage objects, incorrectly freeing kernel memory. An unprivileged local user can read freed kernel memory and escalate privileges. Affected: all supported versions prior to...

CVE-2026-49427

CVE-2026-49427 is a use-after-free vulnerability in FreeBSD's POSIX largepage shared memory objects (posixshm module). Pages in largepage objects were not explicitly wired, so when sendfile(2) transmitted such an object with the SF_NOCACHE flag, it freed underlying pages while existing mappings s...

CVE-2026-49422

The FreeBSD advisory (FreeBSD-SA-26:43.tcp) confirms the bug affects all supported FreeBSD versions and provides specific correction commit hashes for stable/15, releng/15.1, releng/15.0, stable/14, releng/14.4, and releng/14.3 branches, all dated 2026-06-30. Workarounds include not loading tcp_r...

The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...

CVE-2026-49422 Use-after-free in TCP RACK stack option handler

The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control block. If userspace...

CVE-2026-49419

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-72276

A flaw was found in the metronomefb framebuffer driver within the Linux kernel. This vulnerability occurs because memory allocated for page references is not properly released when an error occurs during initialization. A local attacker could potentially exploit this to cause a denial of service...

CVE-2026-49419

FreeBSD 15.0+ kernel contains a double-free bug in kern_jail_set() and kern_jail_get(): when the JAIL_AT_DESC flag is used, the caller's current prison reference is released before descriptor lookup, then released again on error paths. An unprivileged local user can trigger a prison reference cou...
